The angle between two flat mirrors is changed by rotating one of the mirrors around the edge of another with a constant angular velocity \( \omega=1.5 \mathrm{deg} / \mathrm{sec} \). Source of light \( \mathrm{S} \) is located as shown in Figure, the
P distance \( h=10 \mathrm{~cm} \). At the initial moment mirrors were in the same plane \( \left(\varphi=180^{\circ}\right) \).

W
After what minimum time (in second) 3 images will be formed by the mirrors.
